The first months of the year 2020 were characterised worldwide by a single nightmare: Corona. Dreadful images took wing from China, then from Italy, followed by other countries. Projections on how many countless deaths would occur were coupled with pictures of panic buying and empty supermarket shelves. The media in everyday life was driven by Corona, morning, noon and night for weeks on end. Draconian quarantine measures were established all over the world. When you stepped outside, you found yourself in a surreal world – not a soul to be seen, but instead empty streets, empty cities, empty beaches. Civil rights were restricted as never before since the end of the Second World War. The collapse of social life and the economy were generally accepted as being inevitable. Was the country under threat of such a dreadful danger to justify these measures? Had the benefits that could possibly be gained by these measures been adequately weighed against the subsequent collateral damage that might also be expected? Is the current plan to develop a global vaccination programme realistic and scientifically sound?
